This is working fine by centering the user's current location on the map. But I would like to show an indicator (a red dot) on the user's location. But I can see that google API provide only 3 options center, zoom and mapTypeId.

Are there any available options that can be used to highlight the position or is there a workaround?

EDIT

Was able to find that google maps API has a marker ho highlight any position. That looks helpful, but that shows a default red balloon, can that be modified by a custom image?
